Abstract

A document turnover device for reorientating in reversed position a document fed from a copier capable of duplex copying, is illustrated in three different states in Figs. 1, 2, and 3. The document feed path illustrated by dotted line 10 enters from a copier capable of producing duplex copies and is the feed path leading to a collator. When duplex copies are being produced, it is necessary to turn the copy over to provide its appropriate orientation prior to depositing it in a collation apparatus, in order to provide properly collated sets.

Sheet Turn Around Mechanism

A document turnover device for reorientating in reversed position a document fed from a copier capable of duplex copying, is illustrated in three different states in Figs. 1, 2, and 3. The document feed path illustrated by dotted line 10 enters from a copier capable of producing duplex copies and is the feed path leading to a collator. When duplex copies are being produced, it is necessary to turn the copy over to provide its appropriate orientation prior to depositing it in a collation apparatus, in order to provide properly collated sets.

When the copier is in the duplex mode and the collator is operating, deflector member 12 is activated to be effective in deflecting any documents from feed path 10, and thus divert the documents around pinch roll 14 and further be guided by guide member 16. The document is thus driven around roll 14 and into the nip formed between pinch roll 14 and driven roll 18. Driven roll 18 is driven by a geared periphery 20 by being engaged with driving roll 22 through driving gear 24.

Drive roll 18 and pinch roll 14 are maintained in frictional engagement by tension spring 26. Driven roll 18 and pinch roll 14 are also carried on a pivotable cam follower 28. Cam follower 28 is biased into engagement by timed rotating cam 30 to provide an oscillatory movement to follower 28. When follower 28 is at the high dwell of cam 30, pinch roll 14 is pulled by tension spring 26 into frictional engagement with idler roll 18. Thus, as a document is fed along feed...
